Which of these is best used for displaying frequency distributions when one or two categories make up a large proportion of the total?
The answer depends on what is meant by two or more. If it refers to around 4 to 7 then a pie chart may be best: it depends on whether it is appropriate to lump all the remaining categories as an "other" category.
If there are 6 or more categories then a bar chart may be appropriate but again, that depends on whether lumping the remainder together as an "other" category makes sense.

What is best used for displaying frequency distributions when one or two categories make up a large proportion of the total?
a bar graph is best. If it's two categories make sure you have different colors/pattern to differentiate between the two categories. You should also include a key to tell you what each color/pattern representsBar chart
What table lists the categories of a variable and gives the proportion of observation for each category?
A frequency table. Learn to read your Statistics book next time.
Why are open-ended frequency distributions necessary?
to quickly and effectively represent data
What are some benefits of using graphs of frequency distributions?
Graphs of frequency distributions provide a clear visual representation of data, making it easier to identify patterns, trends, and outliers. They simplify complex data sets, allowing for quick comparisons between different groups or categories. Additionally, such graphs can enhance understanding and communication of statistical concepts, making them accessible to a broader audience. Overall, they serve as valuable tools for data analysis and interpretation.
What are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.

What does frequency mean in mathematical from?
In mathematics, frequency refers to the number of times a particular value or event occurs within a specified dataset or interval. It is often used in statistics to describe how often a certain outcome appears, such as in frequency distributions or histograms. Frequency can be expressed as a raw count, relative frequency (proportion of the total), or cumulative frequency (accumulated totals). Understanding frequency is essential for analyzing patterns and trends in data.
What are facts about frequency table?
A frequency table is a statistical tool used to organize and display the frequency of different values or categories in a dataset. It typically includes columns for the categories, their corresponding frequencies (counts), and sometimes relative frequencies or percentages. Frequency tables help to summarize large amounts of data, making it easier to identify patterns, trends, and distributions. They are commonly used in various fields, including research, business, and education, for data analysis and interpretation.
What is a frequency distributions?
The frequency distribution shows in a graph or a table all the possible values of a variable, called the random variable, and the frequency or the count of each value. For example, if you had the ages of 100 people you could do a frequency distribution and split the ages into 10 year categories and then show how many of the 100 people were in the 20s, how many in their 30s, how many in their 40s and so on.
Can frequency distributions contain more than ten observations?
Yes.
What are three types of frequency distributions?
1) Ungrouped2) Grouped 3) Qualitative

What are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.
Does a bar graph have gaps?
Yes, a bar graph typically has gaps between the bars. These gaps indicate that the data represents distinct categories, emphasizing that the values are not continuous. In contrast, a histogram, which displays frequency distributions, does not have gaps because it represents continuous data.
Could a frequency table count the number of times a certain piece of information appears in a data set?
Yes, a frequency table can count the number of times a specific piece of information appears in a data set. It organizes data into categories and displays the frequency of each category, allowing for easy identification of how often each value occurs. This makes it a useful tool for summarizing and analyzing data distributions.
